Question

State the square completing formula..​

Answer 1

Completing the Square

Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial .

To solve ax^2+bx+c=0 by completing the square:

1. Transform the equation so that the constant term, c , is alone on the right side.

2. If a , the leading coefficient (the coefficient of the x^2 term), is not equal to 1 , divide both sides by a .

3. Add the square of half the coefficient of the x -term, (b/2a)^2 to both sides of the equation.

4. Factor the left side as the square of a binomial.

5. Take the square root of both sides. (Remember: (x+q)^2=r is equivalent to x+q=±√r .)

6. Solve for x .

Answer 2

answer: -

Steps

Step 1 Divide all terms by a (the coefficient of x2).

Step 2 Move the number term (c/a) to the right side of the equation.

Step 3 Complete the square on the

left side of the equation and

balance this by adding the same

value to the right side of the

equation.
